Doclunent Number: New Project Prodosal Virginia Carbon Filter Product Projec: .Yanager: Or, C.R, Jsnkins Objective To explore the effect cn the chemical and sensory characteristics and ultimately consumer acceptability of a Virginia cigarette with activated carbon in the filter. Baekoround Clr~on filter cigarettes are important in only 3 markets in the world (;apan, Vene~uela and Switzerland), In each of these arkets, tL.e taste e~racteris:ics of the products ate rather different from that of a Virginia cigarette. In addition, there have been niche 3Eoduets available in the U,S,A, for any years (e,g, Lark) which have not ~d a major impact on the narket, Historically in the U,K,, the largest selling low tar product, Silk Out KS, originally carried a F~kn dual Hirer. As the brand's market share increased, Wle level ci carbon was progressively reduced and ultimately the dual filter was phased out in favour of a single C.A. filter without carbon. Some years ago work was carried out in RbD On the effect of carbon filters on the sensory characteristics of a range of blends: this identified t~t the so-called carbon off-taste was ~Klst easily discerned on a virginia blend. mis loff-taste' was later found to be associated with the imbalance in the smoke created through the removal by the earkn of a portion of the volatile and semi volatile components of swke. The partial removal of these components also resulted in a reduction in irritation levels co~n~red to a similar product wi~put a carb3n filter. lecently there has been some evidence that carbon filter cigarettes tin particular Lark) have been appearing in markets in the sub-mntiner,:, which are essentially flue-cured wtkets. There syl therefore, ~ an opportunity for a carbon-filter Virginia product. eroier, pt3asal TI:e initial phase of this project will, therefore, explore the effect on the che~eal and sensory characteristics of a Virginia Fn~ohet, using a dual aceta:e filter with 60mg of carbon in the 'tobacco' section of the filter las used by Bigott in venezuela - the largest producer of w~n filter cigarettes in the Group), The rationale f:r using this style of filter is that from other studies it has been found it is ~ore efficient for removing vapour phase smoke components :~an a granular bed triple filter, bl:hPugh it might be are appropriate to study the effect of carbon filters only on a low tar product ~as these filters cduld be construed as of:dng swap fonr, of Ihealth rsassu:lnce') in this study bcth a full f:avour prcduet IB&H S~ C~) ex BAT IVT&E) and a low tar C product (B&~ Special Mild ax Belgium) will be examined.

For each pair, it is intended to match the tar and nicotine deliveries of the conacl (parentl product, mese cigarettes will be manufactured and full chemical, physical and sensory analysis carried out to establish the degree of bste change between the carbon filtered version and the conventional product, [Since these filters are p;asticised during goductien leading to a reduction in the activity of the carbon, consideration could be given to asking Biqott to ~Mnufacture filters in which no plasticiser was used in the 'T' section as this will allevnximum activity to be retained in the wbonl, Taste differences are to be expected between the control product and the carbon filter versions. However, no recent research tL3S been csnducte~ to test c3nsuwr reaction to the taste differences, Subject to satisfactprl performance of the products, consideration should be given to eoduc~~q a consumer test in a European r~ket, In phase two, the effect on sensory characteristics ad chemical analyses of ';atehed' products F~oduced using different weights of carbon of differing activity will be examined, namely: Filter (1) - m3derate weight of a high activity carbonl Filter (2) - kigher weight of a lower activity car~n; these tilters being catched in their efficiency for removing aldehydes from smoke but say offer differing revels of off taste. I: is proposed 0 explore this effect on ~Qth full flavour and low tar products. In phase 3, the influence of different Ei'qarette designs on the perception of the 'taste distortion' will be explored. In this phase, the ~Minstrebm tar and nicotine deliveries of the products will be matched but thess deliveries wilr be achieved using cigarette constructions which differ in their consumer demand resgonsiveness! The same weight of carbon will be used for all versions.
